2 Claims.

This invention relates generally to oil burning equipment, and is a division of my co-pending application, Serial No. 88,736, filed July 3, 1936.

While not so limited, my invention is intended particularly for use on marine vessels, wherein it is proposed to bulkhead the fire room thus dividing the latter into a boiler compartment and an operators compartment, said bulkhead being air tight and water tight, and hence, one of said compartments is protected in case the other is flooded with water or filled with gases.

As will presently appear, oil burning equipment, including burner and air register units, is positioned between the boiler front and the bulkhead and suitable means is provided to provide an air tight and Water tight connection of the burner equipment with relation to said bulkhead.

In that it is frequently necessary to remove the burner tube from ts jacket, it is of vital importance that the passage within said jacket be closed in order to prevent the flow of gases from the boiler or boiler compartment to the operators compartment, or the passage of water from the operators compartment to the boiler and boiler compartment in the event said operators compartment should be flooded.

It is therefore, the object of the invention. to provide means adapted to automatically close the burner jacket against pressure flow in either direction when said burner tube is removed, which otherwise would leave an open passage through said bulkhead.

Other features and advantages of my invention 'will hereinafter appear.

In the drawings:

Figure l. is a front elevation showing a bulk-' head in a fire'room with the burner portionsprojecting forwardly thereof.

Fig. 2 is a sectional view, taken on the line 2-2 of Fig. 1, showing the burner equipment mounted on the boiler front plate and the bulkhead.

Fig. 3 is a sectional detail of the rear portion of the burner equipment with the burner tube removed and the burner jacket closed.

Referring now more in detail to the accompanying drawings, wherein like characters of reference denote similar parts throughout the sev oral views, let i indicate a bulkhead which exlends transversely across the the room and serves as an air and water tight partition to separate a boiler compartment A from the operators compartment B, the latter being adapted for human occupancy at atmospheric pressure; it being intended to supply air under pressure, by any suitable means. into compartment A for combustion purposes.

The oil burning equlpment, which comprises burner and air register units, is positioned be- 5 tween the bulkhead l and the boiler front plate 5, certain operative parts of said burner unit projecting into the compartment B, as shown.

For illustrative purposes only, and not in any way restricting the invention,-I have shown the oilburning equipment included in my c'o-pending application, Ser. No. 88,736, wherein the air register unit is shown as provided with a pressed steel frame having divided members 2 that are engaged by studs 3 with a ring Q that is secured ,to the plate 5, said ring also carrying the usual Venturi ring ii. Members 2 extend forwardly to a disk i that is provided with slots 8 for pins 9 that project from curved vanes it which are housed within frame members 2, said vanes havings lugs it by which they pivotally engage studs 3. The rotatable plate it has slots l3 which en'- age pins 9, said plate carrying a toothed sector It operatively connected with pinion l5, the latter having an operating shaft it with handle H for its manipulation. A burner tube l8, with the usual atomizer l9 and flame cone 20 entered within the register, has jacket 2 l, the latter being carried by a hollow casting 22, in which it is rendered 'air tight by a stufling box 23, said casting being provided with a passageway for the shaft it and here a stufilng box it is employed to render the fit air tight between shaft l6 and its passageway. A radial web supports one end of an expansion bellows it, the flange 21 being clamped between said web and a ring 283 as with bolts 25, the other end of said bellows being provided with a flange that is clamped between bulkhead i and a ring 30 asv with bolts 32. As explained in the aforesaid co-pendlng application, the purpose of the expansion bellows is to absorb expansion and other distortions occurring between the bulkhead and boiler. Obviously, the expansion bellows will not be used in many installations, it being of prime importance, of course, that the burner used should make an air tight connection with said bulkhead. I As shown in Fig. 2, the disk I is apertured for the reception of the reduced portion 33, and the IQ- tatable plate 52, which is also apertured, has its hearing about a shoulder it upon said casting, said plate being provided with a cover 35. A

- cover plate 3% is shown as carried by bulkhead i,

and having the observation doors 3! and lighting door 38.

As shown in Fig. 2 the end of the burner jacket I 2|, projecting into the operators compartment B, carries a housing 39 having a cover plate 40, a coupling yoke 4| being pivotally carried by said housing, as indicated at 42, and, adapted to clamp the member 43 in the position indicated, said housing and member 43 being provided with bores to permit the flow of the oil from a source of supply to the burner tube. It will also be noted that said member 43 is provided with an enlarged bore 44 to support one end of the burner tube l8, and that flap valve 45 is pivotally supported within said housing 39'and another flap valve 46 is pivotally disposed exteriorly of said housing. Normally the aforesaid parts are in the positions indicated in Fig. 2, but when it is necessary to remove a burner tube the hand screw 4? is manipulated so that said yoke 4i now assumes the position shown in Fig. 3, member 43 being uncoupled, and finally said burner tube is withdrawn from its jacket. In such instance the jacket 2|, without the use of valves 45 and 46' would afford a free passage for water or gases in either direction past the bulkhead. Hence, the valve 45 will close by gravity against a .seat 48, and thus the flow of water or gases from compartment A into compartment B is prevented. As means of visual indication that valve 45 is closed, it being 1 concealed in housing 39, said is withdrawn, and thus prevent the flow of water or gases from compartment B to compartment A. In view of the foregoing it is obvious that the burner jacket is protected from pressure flow in either direction.

Variations within the spirit of the invention and scope of the claims are equally comprehended by the foregoing disclosure.

I claim:

1. The combination with oil burning equipment including a burner jacket and a burner tube removably encased therein, of. a housing engaging and in communication with said jacket at one end, said housing being provided with inner and outer valve seats, and valves adapted respectively to engage said seats and close said jacket against pressure exerted in either direction when the burner tube is removed from the jacket.

2'. The combination in a fire room having a bulkhead dividing it into a boiler compartment and an operators compartment in which substantially different pressures are maintained, of a hollow casting secured to said bulkhead and projecting into the boiler compartment, a burner jacket mounted and sealed within said casting and projecting into the operators compartment, a. burner tube removably mounted within said jacket, a housing connected to one end of said jacket, said housing being provided with inner and outer valve seats, and valves hingedly connected to said housing and adapted respectively to engage said seats and close the passage in said jacket against pressure exerted in either direction when the burner tube is removed from the jacket.
